More isn't always better: Too much calcium has risks. Dietary calcium is generally safe, but more isn't necessarily better, and excessive calcium doesn't provide extra bone protection. If you take calcium supplements and eat calcium-fortified foods, you may be getting more calcium than you realize.
Genetic Recombination in Bacteria. This is a process where genetic materials, contained in two separate genomes, are brought together within one unit. In bacteria the recombination takes place by (1) transformation, (2) transduction and (3) conjugation.
The Genetics of Recombinant DNA. Recombinant DNA is the process of merging genes from one organism with the genes of another organism. The most common method to complete the process involves using restriction enzymes to isolate a gene and then place it on a vector plasmid.
